A holder, designed for the shower, for a couple disposable razors and a Phillips Norelco [https://www.amazon.com/Philips-Norelco-GoStyler-FS9185-49/dp/B00QYOSKFS is as close as I can find]. Been using it for months and I've seen no degradation at all. It's printed using PLA, but if I experience some issues with it I'll reprint it using PETG or the filament of the moment. I've attached it to the wall using 3M Exterior Mounting Tape [https://www.amazon.com/gp/product/B00004Z4BV] and some Caulking to keep the water from getting behind it.
As a note, the 3M Exterior Mounting Tape is fantastic to keep around the house. It creates a strong bond and it can be removed without affecting most finishes. I keep a couple rolls of the 3M mounting tape around.
Edit: Feel free to edit this creation as you see fit.
